- Information About Kidney Failure

- ------------------------------------------------------------------------------
-
- QUESTION: Just the word "failure" is enough to make me shudder, but I need to
- understand a lot more about kidney failure. Just what does this mean, how
- does it effect someone's life, or is life possible with kidney failure? We do
- not live in the same city as the relative for whom we are concerned, and hope
- you can provide us with this information. Please?!

- ANSWER: The word "failure" has many negative meanings, and nowhere is it a
- more threatening term than when used to describe the state of the kidney. To
- understand what failure means, it is important to appreciate all the important
- functions the kidneys perform when they are working normally. While solid
- wastes leave the body as feces, and gaseous waste products (such as CO2)
- depart by way of the lungs and exhaling, the liquid wastes leave by way of
- sweat to a slight degree and through urine for the most part. And it is the
- kidneys that control that function.
- Many of the chemical processes in the body that lead to the development
- of proteins use amino acids. Proteins form more than 10 percent of the
- body's weight. Amino acids that remain after the body has used all it
- requires are converted into urea by the liver, another waste product that
- must be excreted from the body. And the passage out of the body for urea is
- through the filtering mechanism of the kidney. Urine is thus composed of
- water and urea, with a number of other chemicals as well.
- When the kidneys are unable to filter these waste products out of the
- blood, the wastes stay within the body, causing the symptoms associated with
- kidney failure and impairing the functioning of many body systems. The three
- major causes of kidney failure are the interruption of sufficient blood flow
- to the kidneys (an obstruction of the renal artery for example), poisoning
- with toxic substances that can destroy kidney tissue (heavy metals or some
- types of industrial solvents), or infections or inflammations of the kidney
- itself (nephritis).
- There are two type of kidney failure, "acute" and "chronic". The acute
- type is the result of a rapid deterioration of kidney function, often the
- result of accidents, severe bleeding and shock or chemical toxins. Immediate
- treatment is a must, for this is a life threatening condition. Chronic
- failure develops more slowly, sometimes over a period of years, as bit by bit
- the kidneys lose tissue, and the ability to perform the filtration function
- that is the kidney's responsibility. The patient grows weaker, loses weight,
- develops high blood pressure. Often the mental processes become dulled, there
- are frequent headaches, and gastrointestinal (GI) symptoms such as vomiting,
- stomach cramps, and even GI bleeding can occur. The most common cause of this
- form of failure is glomerulonephritis, but long term untreated high blood
- pressure can also lead to this serous disease. As the kidney fails the toxins
- accumulate in the blood, and both blood and urine tests can provide the signs
- necessary to make a diagnosis. This condition is frequently called "uremia"
- (urine in the blood), and almost every system in the body is affected when
- this occurs.
- As the severity of the disease progresses, there are only two possible
- therapies that can offer relief. The first is kidney dialysis, where the
- blood is cleansed artificially by using a machine to perform the work the
- kidneys no longer can do. The other, more preferable treatment is a kidney
- transplant. Unfortunately, there are far more people needing this operation
- than there are organs. Let this be my plea to all who read this column, to
- consider including organ donation when they make their plans for the
- inevitable that must come to us all.
